Spring和ExtJS“400 Bad Request”与PUT但不是POST [英] Spring and ExtJS "400 Bad Request" with PUT but not with POST

问题描述

我正在尝试使用PUT从JavaScript发送参数到Spring应用程序。这是Spring控制器中的@RequestMapping：

I'm trying to send parameters with PUT from JavaScript to a Spring application. Here is the @RequestMapping in a Spring Controller:

@RequestMapping(value = "toggle-paid-action", method = RequestMethod.PUT)
@ResponseBody
public final String togglePaid(@RequestParam final int year, 
    @RequestParam final String docType, @RequestParam final int number) {

这里是应该发送这些参数的JavaScript代码段。

And here the JavaScript snippet that is supposed to send those parameters.

Ext.Ajax.request({
    params: {year: year, docType: docType, number: number},
    url: 'toggle-paid-action',
    method: 'PUT',

然而，我每次都收到一个400错误请求描述客户端发送的请求在语法上不正确（）。

However, I get a "400 Bad Request" every time with description "The request sent by the client was syntactically incorrect ()".

如果我使用Firebug检查，有一个PUT选项卡，其中包含所有参数，参数是正确拼写，因为如果我从PUT切换到POST两边都有效。

If I check with Firebug, there is a PUT tab with all my parameters, and the parameters are correctly spelled since if I switch from PUT to POST on both sides everything works.

我在想什么可能是问题，PUT是否限于@PathVariable参数，还是可以发送类似POST的参数？

I was wondering what could be the problem, is PUT limited to @PathVariable parameters, or it can send also POST-like parameters?

推荐答案

您不能使用请求方法PUT来传递参数，因为servlet API中有一个限制。在其他情况下（如Spring MVC Databinding），您只能使用PUT方法实现一个安静的服务，传递数据作为请求正文，否则PUT将无法正常工作。
请参阅 SpringMVC无法识别请求体参数如果使用PUT

I suppose you can't pass parameters to spring using request method PUT as there is a restriction in the servlet API. You can only work with PUT methods implementing a restful service, passing data as the request body, in other cases (like Spring MVC Databinding) PUT won't work. see SpringMVC is not recognizing request body parameters if using PUT
